<P>PROBLEM TO BE SOLVED: To provide a novel epoxy resin composition which enables long-term storage without causing crystallization, phase separation and the like and can form a cured product hard to cause yellowing deterioration by heat. <P>SOLUTION: The epoxy resin composition is composed of component (A) of an optionally substituted triglycidyl isocyanurate modified with a carboxylic acid and component (B) of at least one epoxy resin which is selected from the group consisting of a hydrogenated aromatic epoxy resin, an alicyclic epoxy resin, and an aliphatic epoxy resin and is liquid at 25°C, is obtained by mixing 100 pts.mass component (B) with 10-900 pts.mass component (A), and has a modification ratio in component (A) [the molar amount of a carboxy group present in one mole component (B)] of 0.1-2.0 moles. <P>COPYRIGHT: (C)2008,JPO&INPIT |
